Vertical Shaft / Kingpin — 185×25mm, PN 24234-32181
The 24234-32181 vertical shaft is a hardened kingpin shaft measuring 185mm in length and 25mm in diameter — the main pivot pin around which the forklift steering knuckle rotates on the rear axle. This is the individual kingpin shaft (vertical shaft) without bushings, thrust washers, or seals — intended as a replacement when the shaft itself is bent, scored, or worn but the bushings and hardware are still serviceable. A bent 24234-32181 vertical shaft causes binding in the steering at certain angles and accelerated bushing wear, while a scored shaft surface acts like a file against the bushings with every steering movement.
Manufactured from heat-treated alloy steel with a precision-ground surface finish and chamfered ends, this vertical shaft matches the OEM 24234-32181 specification for length (185mm), diameter (25mm), and hardness. Verify the shaft dimensions against the removed component before ordering. For complete king pin kits with bushings and seals, browse our forklift hydraulic components.
